    摘要: The present invention relates to a method for the manufacture of highly purified 68 Ge material for radiopharmaceutical purposes. The invention particularly concerns the production of 68 Ge-API (API = Active Pharmaceutical Ingredient) solution complying with the Guidelines for good manufacturing practices (GMP). Starting material for the method of the present invention can be a 68 Ge stock solution of commercial or other origin as raw material. Such 68 Ge containing raw solutions are purified from potential metal and organic impurities originating from production processes. The radiochemical method disclosed is based on a twofold separation of 68 Ge from organic and metallic impurities with two different adsorbent materials. During the first separation phase 68 Ge is purified from both organic and metallic impurities by adsorption in germanium tetrachloride form, after which hydrolyzed 68 Ge is purified from remaining metallic impurities by cation exchange. The final 68 Ge-API-product e.g. fulfills the regulatory requirements for specifications of the GMP production of 68 Ge/ 68 Ga generators.

    摘要: Es wird ein Herstellungsverfahren für Halogenide des zweiwertigen Germaniums als Addukte mit einem Ether, insbesondere von Addukten mit der Formel GeX₂·(C₄H₈O₂), wobei X bevorzugt Chlor oder Brom bedeutet und als Ether bevorzugt 1,4-Dioxan verwendet wird, beschrieben. Germaniumtetrahalogenide lassen sich in Gegenwart eines Ethers, eines Organosilans und zumindest katalytischer Mengen eines Metallhydrides in einer einstufigen Reaktion und mit hohen Ausbeuten zu den Zielverbindungen reduzieren.

    摘要: The invention relates to a system and method for the recovery of germanium from the Modified Chemical Vapor Deposition (MCVD) processing wastes by chemical conversion and recovery of germanium from the solid cake product. In the present method, the direct reaction of gaseous hydrogen chloride with the recovered materials effects the rapid and complete chlorination of the germanates, yielding germanium tetrachloride. The germanium tetrachloride product is completely volatilized and removed from the mixture during the exothermic process.
